ABSTRACT:
An air sampling system includes a chamber that is formed with an exhaust port and a plurality of intake ports. A plurality of air collector arms are each attached in fluid communication with a respective intake port of the chamber. Further, each collector arm is formed with an inlet slot and an air channel which establishes fluid communications between the inlet slot and the respective chamber intake port. All of the collector arms extend outwardly from the chamber so that their respective inlet slots lie in a first plane. Relative to the inlet slots, the exhaust port of the chamber lies in a second plane that is substantially parallel to the first plane. Accordingly, a portion of the air that passes through the first plane toward the second plane, enters the inlet slots of the collector arms and is diverted into the chamber. In the chamber the diverted air is redirected out the exhaust port. A sensor mounted on the chamber at the exhaust port measures selected characteristics of the diverted and redirected air at the second plane to sample the air that is flowing through the first plane.
